Hello Kam!
The wire feeder having a pulser will not give you true pulse capability with any non-pulsing power sources. The only way you can achieve this is by having either a built in circuit in the power source that gives you the option or a kit provided by the equipment mfr. that's purchased as an option. What I mean by this is that you need to have the pulse circuit in the power source in order to achieve true pulsing in the welding circuit. Voltage sensing wire feeders alone will not give you true GMAW pulse welding arc characteristics.
At least this is what I remember from my days as a Welding Equipment Repairperson. However, I may not know all of the many advances in the welding equipment available today. Could you please elaborate more on the type of wire feeder you're talking about? No Offense!
By the way, you're right about sounds when comparing short circuit to pulse spray. If you work with automated equipment such as robots, then you know that the power sources used with robotic cells are'nt your average "machines" . ultimately you have to have some sort of interface from the wire feeder to the power source especially on robots which are interfaced with the controllers. Unless I'm mistaken or missing something?
